They are all questions to which there are no answers

题目

They are all questions to which there are no answers
这是个定语从语,为什么要用to which引导呢,which为什么就不行呢?而且"to which"在定语从句中什么成份啊?
那么to which在从句里是代词,类似状语的成份啦

答案

to 被提前了.answers to the question 是固定搭配
是关系代词（不是关系副词哦!）
如果是in（or at,on etc.） which 代表地点的话 就相当于 where 就是关系副词了!
